Diseases always strike a heavy blow to our health without notice. When people around you have headaches, blurred vision, seizures, and eye movement disorders, be sure to be alert to hydrocephalus, which is likely to be some early distress signal from your body to you. Hydrocephalus is more common in infants, and some infants may suffer from congenital malformations, intracranial infections or tumors shortly after birth, causing serious harm to intelligence and physical development. In addition, in recent years, the incidence of hydrocephalus in the elderly has been gradually increasing, which not only brings great mental stress to the family, but also leads to a greatly reduced quality of life and a diminished interest in life. In the long run, it will easily lead to great psychological problems. As a result, hydrocephalus should not be taken lightly and early treatment is a viable strategy. The treatment option for hydrocephalus is to have a shunt. When it comes to shunts, it is important to talk about some of the shortcomings of conventional shunts to avoid patients taking more detours in the treatment process. The advantages of conventional bypass are simple operation, short time and little trauma. However, its disadvantages also need to be paid attention to, not only can infection and blockage occur, but also can cause many sequelae such as bypass tube fracture, which undoubtedly brings more harm to patients.
